Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503220, here are decompositions:

7 + 503213 = 503220
13 + 503207 = 503220
23 + 503197 = 503220
61 + 503159 = 503220
73 + 503147 = 503220
83 + 503137 = 503220
89 + 503131 = 503220
97 + 503123 = 503220

Showing the first eight; more decompositions exist.
